Hi Claudel
I think 183 and 168 are good candidates for restoration because they are so intact and are in at least a basic level of preservation. It wouldn't take much effort to get the Chippy running because the engine is a simple one and the wing mods are comparatively simple to carry out.It is the best candidate of all the aircraft there, apart from the Marchetti. I accept that the Leonides on the Provost would be harder to restore to running order, but, again, it's not insurmountable.
There is a Chippy based at Kilrush, near Athy, owned by an ex-Air Corps/Air Lingus pilot and it is airworthy.It is still in it's UAS colours. I have flown in it twice and it is delightful to fly. All the more reason to get 168 flying again.In real terms, it would cost a few thousand to get it flying, a sum that the AC could find, I'm sure. There are discretionary funds in the annual budget, subject to the nod of the GoC. I'm sure a well-written request for a seed budget would go a long way.
My toolbox are ready! Just give me the nod and we could get 168 to taxying condition in short order.
